Protonet got 3 Mio EUR last year in a crowd funding campaign in Germany for their NAS + collaboration software, with a clear marketing focus on privacy ... so no, it's still a market ;)
Yeah, we got a Protonet Maya some time ago and it's been pretty much a paperweight + expensive wireless router so far. The software is ambitious but ultimately useless.
Funny enough, our biggest boost in communication came from starting using Slack. That thing is amazing, and getting creative with integrations is awesome. It's a somewhat important part of our workflow now.
